MRS Bulletin, 2004
AbstractThe use of multivariate data analysis combined with sensors with partially overlapping selectivities has become a very powerful tool in measurement technology. These systems are often referred to as artificial senses, because they function in a way similar to the human senses. One such system is the electronic nose.

Microfluidic electronic tongue
Sensors and Actuators B: Chemical, 2015Fast, simple inspection of liquids such as coffee, wine and body fluids is highly desirable for food, beverage and clinical analysis. Electronic tongues are sensors capable of performing quantitative and qualitative measurements in liquid substances using multivariate analysis tools.

Recent advances in electronic tongues
The Analyst, 2010This minireview describes the main developments of electronic tongues (e-tongues) and taste sensors in recent years, with a summary of the principles of detection and materials used in the sensing units. E-tongues are sensor arrays capable of distinguishing very similar liquids employing the concept of global selectivity, where the difference in the ...

Electronic tongues in flow analysis
Analytica Chimica Acta, 2007This review presents the evolution of recent flow-based analytical systems, characterized by the use of arrays of sensors as a detection scheme. For the proper processing of the complex responses generated, the systems require the use of advanced chemometric treatment, in which received the term "electronic tongue".

Electroanalysis, 2015
AbstractWe present a low cost paper‐based electronic tongue capable of discriminating forged water samples. System comprises of 4 paper‐based potentiometric sensors (sensitive to Cl−, Na+/K+, Ca2+/Mg2+, ${{\rm NO}{{- \hfill \atop 3\hfill}}}$) and a traditional Ag/AgCl reference electrode.

Advanced electronic tongue concept
Proceedings, IEEE Aerospace Conference, 2003This effort, directed at developing a sensor for evaluating water quality, is based on electrochemical techniques that detect and identify ions in solution. This paper discusses the use of Cyclic Voltammetry (CV), corrosion measurements, and Anodic Stripping Voltammetry (ASV) to measure three marker ions Cu, Fe, and Zn using the electronic tongue ...

Electronic Nose and Electronic Tongue
2010Human beings have five senses, namely, vision, hearing, touch, smell and taste. The sensors for vision, hearing and touch have been developed for several years. The need for sensors capable of mimicking the senses of smell and taste have been felt only recently in food industry, environmental monitoring and several industrial applications.

Electronic Nose and Electronic Tongue
2015The sensations of smell and taste resulting from a series of specific and nonspecific molecular recognition can be used as an analytical tool in many industries to measure the quality of food, drinks, and chemical products. In a few cases, there are olfactory receptor s or gustatory receptors which are specific for individual chemical molecules ...

Sensors and Actuators B: Chemical, 2012
Abstract In this work a novel electronic tongue (ET) using Fourier transform impedance spectroscopy has been demonstrated. Odd random phase multisine waveform has been used as an excitation signal. Texas Instruments’ PCM2900B USB audio CODEC chip has been used as a signal generation and an acquisition module for the ET.
